It’s all over now and I can’t describe how tired I am. As I type it, my flight from Chicago is delayed by 1.5 hour so far (the third delay already, 30 minutes each). I should say that I hate Chicago airport but I digress.

Last night, I left my presentation in a good state and verified the first batch of demos — all worked fine. This morning turned into a disaster as I found out that the rest of my demos stopped working — my 11g RAC cluster on Ubuntu (I have the reason for such unusual setup) got issues with network connectivity. I should probably blame VMware Fusion 2.0 beta combined with Ubuntu but the net result was failing network connections with weird TNS errors and hanging connection requests. Obviously, I couldn’t demonstrate advanced connection management without *simple* connections working.

Well, I didn’t have any other choice but to add new slides with some demo results. Since I did it in a rush, there were some overlaps and I ended up with way too many slides. Good news that the first demo generated sufficiently enough interest about services automation and connection load balancing so we spent significant time there. Well, nothing comes for free so the rest of the presentation had to be covered too quickly but I did manage to go through the failover scenarios and failover technologies available. Run-time load balancing and load balancing advisory wasn’t left aside either so I did make it till the very last slide!

All in all, today’s session wasn’t as good as yesterday but I managed to avoid a complete failure with the demos so I guess I shouldn’t complain.

This morning I checked how the labs went on the 24th floor and I should say that labs agenda looked very impressive and it seems that lab part was probably the best feature of the event. The amount of material Jeremy Schneider prepared was huge and there would be enough labs for 2 full days, not just one. The attendees could choose the areas they are interested in most and work on different threads with their own pace. Great job Jeremy!

Back to the reality and the airport… The flight Chicago-Ottawa is 3+ hours late and they moved us to another gate. Oh… Do I hate Chicago airport! In the meantime I managed to transfer this text from my MacBook to the Blackberry and publishing it from there. The Blackberry syncronisation utility for Mac is a big shame. Can’t wait for iPhone…

To finish on a good note — I’m very glad I came to RAC Attack! What a pleasure to see old friends and make new ones. I just hope I can actually *leave* this place…

I should say that I had interesting experience this evening — a tornado warning in downtown Chicago.

The alarms went off as soon as we tried to get out of the restaurant. Below is a year old example but it sounded exactly like that + it was much darker — like if the skies fell on us:

We had to turn back and were stuck in the pub for another hour or so sipping Guinness while the mother-nature had some fun around us. Funny, looks like it decided to come back now — skies are falling again with heavy rain, clouds and lightnings everywhere. The thunder is very loud and sirens went off again — can’t even sleep. But I digress so let’s get back to the overview of the day…

I love small classes! I mean small rooms with all chairs taken when people are close to me as I present and close to each other. The audience today was exact fit for the room — 20 people could fit on the chairs around the desks and few more (organizers and presenters) next to the back wall. What I like about small classes is the intimate atmosphere in the room. I also like live speech where my voice delivered natively without electronic distortion keeping all the beauty of the Russian accent (some people *still* noticed bits of German influence there).

The only small problem was the location of the stand where a speaker hosts the laptop — it was in the middle of the room. That felt somewhat odd and I kept running between the middle of the room and the stage (well, or the place where it’s supposed to be). I used to the fact that I have another view on my laptop screen — speaker’s view with next slide/motion and my reminders. I also had to do several demo’s on my RAC cluster and I obviously needed the keyboard badly for that. I should apologize that 8 people had to observe my back instead of my face for some time and I also couldn’t see how they were taking the material but I tried to look back from time to time and as soon I did that — I could see confirming nods so thanks for that!
(more…)

Just a quick note that I’m going to present two sessions on the RAC Attack! event in Chicago next week — 4-5 August 2008. The event is organized as two threads — one for advanced RAC DBA’s and another one for beginners. Each thread will have one day of hands-on labs and one day of lectures. Another option would be to choose two days of lectures. More details on the RAC Attack event home page.

I’ll be presenting on both days. The beginner’s presentation will be “Under the Hood of Oracle Clusterware” and the more advanced session is called “Connections! Connections! Connections!”. Now, I’m terribly busy preparing for it — working on the slides (yes, I started earlier than some might expect…) and setting up the live demo.

RAC Attack is organized by IOUG and RAC SIG and, as far as I know, the attendance will pretty good but there are still few places left so you have a chance to register.

What’s for me? Great opportunity to catch up with few old friends and, hopefully, meet some new ones. In addition, I have never been to Chicago so it’s something I really keen to experience while I have a chance.
